What is the importance of high specific heat capacity of water?
Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances. This is why water is valuable to industries and in your car’s radiator as a coolant.
What is the importance of specific heat capacity?
Specific heat capacity is a measure of the amount of heat energy required to change the temperature of 1 kg of a material by 1 K. Hence it is important as it will give an indication of how much energy will be required to heat or cool an object of a given mass by a given amount.
What does having a high specific heat capacity mean?
A high specific heat capacity means it can hold a large amount of thermal energy in for a low mass or temperature change.
Why does water have high latent heat?
The latent heat of vaporization is very high because the amount of energy required to break the hydrogen bond is high. The bounds between the hydrogen atoms must be broken for the molecules to change into a gas.
What has a higher specific heat than water?
Originally Answered: Which substance has a longer heat capacity than water? Among solids, liquids and gases , hydrogen has the highest specific heat (heat capacity).
What does a high specific heat capacity mean?
Why is water high latent heat of vaporization important?
Thus a liquid can flow, unlike a solid. The energy required to completely separate the molecules, moving from liquid to gas, is much greater that if you were just to reduce their separation, solid to liquid. Hence the reason why the latent heat of vaporization is greater that the latent heat of fusion.
Why does water have a high specific heat capacity?
Water is one of the latter—it has a high specific heat capacity because it requires more energy to raise the temperature. Water has a specific heat capacity of 4182 J/kg°C.
What is specificspecific heat capacity?
Specific heat capacity is a measure of the amount of heat energy required to change the temperature of 1 kg of a material by 1 K.
What does a high heat capacity mean in chemistry?
A high heat capacity means that a substance can absorb a lot of heat before registering a change in temperature—think about how long it takes for a pot to get warm to the touch on the stove versus how long it takes the water inside to get warm. That means that water has a higher heat capacity—it can store more heat before changing in temperature.
What is the specific heat of water at room temperature?
This (1 cal/g.deg) is the specific heat of the water as a liquid or specific heat capacity of liquid water. One calorie= 4.184 joules; 1 joule= 1 kg(m) 2 (s) -2 = 0.239005736 calorie The specific heat capacity of water vapour at room temperature is also higher than most other materials.
